Data from two recent Tai chi studies have found that Tai Chi yields symptomatic benefit in patients with fibromyalgia (FM). The purpose of this study is to confirm those findings in a larger randomized, controlled clinical trial in a community-based setting. We also sought to extend this line of inquiry by closely examining Tai chi's effect on physical function, specifically postural stability. Towards these ends, we conducted a single-blind, randomized controlled clinical trial of an FM modified 8-form Yang-style Tai chi program compared to standard education. Subjects in both conditions meet in small groups two times weekly for 60 minutes over 12 weeks.
